Module anim

Expand description

Animation primitives: tweens, springs, keyframes, sequences, and staggers.

All animations are tick-based — call the value() method each frame with the current Context::tick to advance. No timers or threads involved.

Structs§

Keyframes: Multi-stop keyframe animation over a fixed tick duration.
Sequence: Sequential timeline that chains multiple animation segments.
Spring: Spring physics animation that settles toward a target value.
Stagger: Parallel staggered animation where each item starts after a fixed delay.
Tween: Linear interpolation between two values over a duration, with optional easing.

ease_in_cubic: Cubic ease-in: slow start, fast end (stronger than quadratic).
ease_in_out_cubic: Cubic ease-in-out: slow start, fast middle, slow end (stronger than quadratic).
ease_in_out_quad: Quadratic ease-in-out: slow start, fast middle, slow end.
ease_in_quad: Quadratic ease-in: slow start, fast end.
ease_linear: Linear easing: constant rate from 0.0 to 1.0.
ease_out_bounce: Bounce ease-out: simulates a ball bouncing before coming to rest.
ease_out_cubic: Cubic ease-out: fast start, slow end (stronger than quadratic).
ease_out_elastic: Elastic ease-out: overshoots the target and oscillates before settling.
ease_out_quad: Quadratic ease-out: fast start, slow end.
lerp: Linear interpolation between a and b at position t (0.0..=1.0).
